PROBLEM TO BE SOLVED: To effectively remove ozone in a cylindrical body even when an electron irradiation is performed by housing a subject to be irradiated in the cylindrical body in order to keep the electron beam distribution within a specified magnification by discharging the ozone in the cylindrical body from a penetrating section by using a forcible discharging means or a natural convection in the cylindrical body. SOLUTION: A belt conveyor is carried under a state wherein a cylindrical body 1 housing a dialyzer is placed on a mounting base, and an electron beam is beam- irradiated from an electron beam irradiation device. Thus, the dialyzer is sterilized while the cylindrical body 1 rotates in an effective electron beam irradiation region. As a result, the sterilization of the dialyzer wherein a specified dosage is ensured is performed. At the same time, by utilizing the suction force of a fan 1a which synchronously rotates with the cylindrical body 1, an air stream is introduced from a hole 1b to the upper cylindrical body 1A through the lower cylindrical body 1B and the fan 1a, and ozone accumulated in the upper cylindrical body 1A is discharged upward together with the ascending air stream generated by the heating of the electron beam irradiation. Then, the ozone which is immediately discharged to the outside of the cylindrical body 1 in the electron beam irradiation region, is adsorbed by an ozone adsorber in the device, and a purified air only is discharged to the outside of the device. |
